to be wound back and'forth first onto one reel and then onto the other reel. The ribbon 11 extends throu h the. intermediate chamber 4 and throug cut-away portions 1212 formedin the circular walls of the front and rear reel chambers 2 and 3. The

front and rear reels'are-adapted to be set in motion in any suitable manner such as by means of clock work or other well known automatic mechanism, not necessary herein to be specificallyillust-rated and described.

he ribbon 11 on its passage through the intermediate chamber 4 extends over and is guided by a su port 14 which is formed preferabl of bar rubber and is-adjustably supporte by means of a standard 15 which extends through a horizontal 16 with lock nuts or other suitable devices 17 by means of which the support 14 ma which may be adapted either for recording be vertically adjusted. The ribbon 11, a o've' the support 14, is engaged by a. needle 18 or reproducing, said needle being connected with a diaphra which'communicates through a pipe 21 with thehorn 22.

The ribbon 11 is provided in any suitable and well known manner with sound records extending in opposite directions. The needle 18, as shown in Fig. 2, is laterally adjustable, together with the sound chamber 20, in a slot 22 which extends from side to side of the upper end of the intermediate chamber 4. After the record ribbon has been run to one end, the needle 18 is adjusted laterally in the slot 22 and the movement of the ribbon is reversed. The introduction and removal of the reels 10 containing the rib bon 11, and the adjustment of the support 14 are effected by opening the door 5.

The instrument of the present invention is strong, simple, durable and inexpensive in construction as Well as efiicient in operation.

at is claimed 'as new is A sound recorder and reproducer comprising a casing having front and rear reel chambers, an an intermediate chamber, said reel chambers being circular in cross section and said intermediate chamber being provided with a horizontal partition and having a transverse slot at its upper end formed with beveled side walls, a door closing the ends of said chambers, a pair of reels, one of said reels being mounted in the front gm 19 in a sound chamber 20 4L2 m m reel chambereand the other of said reels tapering supporting means adjustable being mounted in the rear reel chamber, a sald'transverse slotat the upper end of sa d ribbon record extending from one of said intermediate chamber.
